Agronomy Notes
Soil moisture conditions can have a large effect on crop responses to nitrogen fertilization. Kentucky's usual climatic pattern of periods of heavy rainfall and relatively warm temperatures during the winter and spring seasons influences expected yield responses of corn to applied nitrogen. If nitrogen fertilizer is applied in late winter or early spring, some of it may be lost before the plants have made sufficient growth to take up appreciable quantities. The amount of loss that might be expected will be influenced by the amount of rainfall, temperature, amount of organic matter and drainage of the soil.

Agronomy Notes
Nitrate nitrogen is the dominant form of plant-available nitrogen in soils, since even ammonium nitrogen is rapidly converted to nitrate nitrogen under Kentucky field conditions. Nitrogen in the nitrate form can be lost by leaching in the drainage water and by denitrification when the soil is saturated with water for a relatively short period of time. With the increased cost and short supply of nitrogen fertilizers, it is especially important that applications be made at a time and in a way that will minimize losses.
